After spending parts of four seasons with the Dallas Cowboys, center Phil Costa entered free agency and signed a two-year deal with the Indianapolis Colts.

It appeared to be a solid match, as the Colts, who had released Samson Satele, were hopeful that Costa would either push the rather disappointing Khaled Holmes to perform better or even win the starting center job himself.
